Lies, damn lies, and benchmarks.

I know as a long-time C programmer, there are small changes I can make to source that will result in big-time performance gains.

Could hinge on how tight their FORTRAN code is vs their C code...

Could also depend on how much love their respective machine code translations have been getting.

Fortran hasn't been all caps for nearly 30 years now...

It is very easy for a physical scientist to write Fortran that performs well - the syntax looks very similar to the maths that is being modeled. It is a lot harder for a scientist to write tight C code.

Not bashing Fortran here, I'm defending it.

Look and you might see measurements of several different C or C++ or … programs doing the same task with different performance.
